Make-or-Buy Decisions in Patent Related Services
No full textAmong the most prominent theoretical frameworks dealing with the economic underlyings of firms’ make-or-buy decisions are Transaction Cost Economics (TCE) and the Resourced Based View (RBV). Relying on panel data covering 107 European firms over eight years I test predictions from both TCE and RBV with regard to the outsourcing of patent related services simultaneously. Modelling the share of outsourced patent applications in a Negative Binomial Panel Regression Model I find joint explanatory power of both approaches. My findings support previous literature arguing for an integration of TCE and RBV to a comprehensive theoretical framework of firms make-or-buy decisions.outsourcing; patent attorney; make-or-buy; negative binomial panel regression

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
The muscle integrity is compromised in <i>gemütlich</i> (<i>geh</i>) mutants.
No full text(A) At 3 dpf, geh mutants appeared unremarkable under bright-field microscopy. (B) In comparison to their siblings, (B’) 3-dpf-old geh homozygotes appeared darker in representative images taken under polarised light conditions. (C) After rescaling to siblings (100 ± 1%), the birefringence of 3-dpf-old geh homozygotes was significantly reduced to 61 ± 1%. Crosses represent averaged birefringence of clutches with a minimum of 6 larvae per genotype (n = 5 clutches). Data are presented as mean ± SEM; *** P geh homozygotes and siblings (n = 6 per genotype). Scale bar sizes are indicated.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
